DJ and producer Prime Cuts from the Scratch Perverts explains why he's using a new music format called Stems, which has been developed by Native Instruments.

Stems software splits a track into four separate musical elements: drums, bass line, melody and vocals. Prime Cuts tells BBC Click's LJ Rich that rather than making life easier for a DJ, the creative options the format brings are 'vast'.

I can see a lot of additional creativity if this sort of 4 track concept format hits the mainstream so folks can rework remix and otherwise toy with their favourite sounds. I dont see it getting any traction amongst RIAA members however as it offers too much freedom to creative folks.
